Adding component to NestedList' items - rendering fails

Adding component to NestedList' items - rendering fails

The result that was expected:
In Sencha Touch 2.0.1 I could pass an component derived from Ext.form.fieldset (containing two selectlists and a textbox) to the items collection of a NestedList component as following:

This would cause the fieldset containing the three components being added on top of the list, and nicely scrolling together with the list items (which are loaded via a Store).

The result that occurs instead:
After upgrading to Sencha 2.1, this no longer works. There is no error message thrown, but the list items are shown on top/over of the 'productsearch'-component. The component is also not interactable (prob. since the list items are rendered over it) and does not scroll with the list.

By coincedence I found the solution in another thread in Q&A. It turns out that for 2.1 you have to add the following properties to the component you want to add to the list:

Code:

scrollDock: 'top',
docked: 'top'

This seems to do the trick. I think it would be good if there was a section telling us about those changes when upgraden from 2.0.* to 2.1? For ex. I cannot find anything in regard to the 'scrollDock' property in the documentation? Anyhow, thanks for your help.
